@RajGovind note that only the last paragraph of this answer is manual - the labelling options are fully automatic

A cumbersome workaround is to copy/paste the layer in the ArcMap TOC, then change its source to the new raster

ArcGIS haiku: yesterday it worked. today it isn't working. Esri is like that ;)

comment Converting Vertices of Polylines and Polygons to Points and Maintain Attributes
It's a bit hard to debug as not all the code is included - can you verify that output_fc contains all required attributes (which I think is what the error message is complaining about)? Can you also break before the with arcpy.da line and check the value of fieldnames?

comment Converting Vertices of Polylines and Polygons to Points and Maintain Attributes
You've used AddField_management on point_file_name but your InsertCursor is working on output_fc - are you sure that output_fc has the required fields?

comment Help needed with query task results to show in dojo Grid?
There must be something outside this script which is switching the grid on and off. You could place some code within the success function of the query to ensure that it's displayed.

comment Using Python to shorten polylines of varying lengths by 44% of their original length (or by a value contained in a field)
+1 for creating a ready-to-use tool, and also sharing the code. We should all do this!

comment Help needed with query task results to show in dojo Grid?
Have you verified that your query task is returning a result? Put a breakpoint on the line "var grid = this.grid" and check whether results contains any features.

comment How to log into ArcGIS Online for organization from ArcMap?
No idea, sorry. I would raise this with whoever set up your Amazon infrastructure, and/or with your local Esri support person as it appears that it hasn't been configured correctly

Sorry, not sure - my situation is the same as yours. What error message do you get when you try this approach?

comment Why is Mosaic or Mosaic To New Image causing a 1-pixel gap between adjacent images?
@Jakub it's weird that I'm seeing the exact opposite - it works well in a file GDB, but gives me an artifact outside of this

comment overlay google maps to openlayers in geoserver
I would start by reading the OpenLayers Getting Started documentation. Then once you have a good grasp of the basics, see the [Google Maps demo].(dev.openlayers.org/releases/OpenLayers-2.13.1/examples/…)

could you be trying to divide by zero? Verify that KM2AREA is not zero for all records

comment Interpolating vertically in 3D analyst
Sorry, this is way beyond me - hopefully someone with more modelling experience can help. While researching this I came across LeapFrog3D which might help if you're able to purchase a new product

comment I'm converting a raster to TIN and a large section of it didn't convert properly (ArcGIS 10)
A trick to aid in verification of the original DEM is to create Slope and Hillshade rasters - these can often show up discrepancies which aren't immediately apparent when viewing the DEM

comment Interpolating vertically in 3D analyst
Great question. This sounds like trilinear interpolation - if so do the algorithms on that page help?

comment How to georeference an image in ArcMap, using coordinates from a KML file
for bonus points, use the Warp command in a script to automate this: arcpy.Warp_management(inImage,"'0 0';'{0} -{1}';'{0} 0'".format(width, height),"'{0} {1}';'{2} {3}';'{2} {1}'".format(west, north, east, south),outImage,"POLYORDER1","NEAREST")

comment How to obtain the width and height of an image using arcpy
Do you want to put that as an answer instead of a comment, and I'll accept it (might be easier to find, etc)
